Product Details
Carriage Bolts are often used for connecting wood to wood, wood to metal and metal to metal。
At the Goshen hardware , we provide you with several high quality Carriage Bolts that are made from premium quality materials and different grades of stainless steel to ensure that these will last for long time.
Typically, carriage bolt sizes range from #10 to 3/4" or M5 to M20 in diameter while lengths span from about 1/2" to 20"—only larger sizes are available in long lengths. Measure length from under the head to the threaded end of the bolt. And it’s often using standard as beloW: DIN607， DIN603 ，ISO 8677，JIS B 1171，ASME/ANSI B 18.5.2.3M，ASME/ANSI B 18.5 ect.If u have drawing of carriage bolt, pls send it to us , we can according your requirement to production. Welcome your inquiry.
